[Discuss-gnuradio] How can we adjust the ADC rate in usrp2 in ofdm benchmark example?
Hi guy, Thanks in advance. I am a new comer to gnuradio. Now I am handling the project based on ofdm benchmark. I want to down-sample ADC to 2M/s(default is 100M/s) to capture the low frequency signal, 1Mhz in our case. I guess the USRP capture all the signal using the maximal ADC rate by default. Does anyone know how to do that? Any help will be greatly appreciated. Best, Kay ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Re: [Discuss-gnuradio] Installation issues with gnuradio on Ubuntu 12.04
You can have custom install locations by telling the build-gnuradio script to not do the build. For example: ./build-gnuradio -m prereqs gitfetch This will perform the resolving of prerequisites, get the source code and use the HEAD of the master branch (which has the very latest commits to GnuRadio). Then you can do the build in a separate step. Chose an install directory that makes sense for you. /opt works well since it has the correct permissions. cd gnuradio mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=/opt/gnuradio .. make sudo make install This will build GnuRadio and install it in /opt/gnuradio The down side is that you'll have to build all the other modules that you need (UHD, gr-osmosdr, gr-iqbal, etc.) one by one. Make sure you use the same install directory with cmake. It should be noted that once you have all the prerequisites on your machine, you don't have to run build-gnuradio again. Assuming you haven't changed any of the prerequisites, you can just git clone GnuRadio and build it like above.

I see this error very often when I install Gnuradio from sources. I then usually install 1.46 and 1.48 and it works. Although it creates some mess. A simpler solution is just use build-gnuradio script http://www.sbrac.org/files/build-gnuradio Magically it installs everything and it doesn't complain about anything. I like to have UHD and gnuradio in custom locations because I keep several versions of gnuradio, UHD and libusrp, but I don't know how to do it with this script. If you don't care about the locations just use the script. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

$ gr-perf-monitorx 127.0.0.1 23456
Hey Dan,
When you're running the flowgraph that you're trying to connect to over
ControlPort, can you verify that they are setting up the correct endpoint?
If you run it yourself, not as a background task, it should print out
information about the endpoints. That will tell you the port number. Just
want to check to make sure your config file is getting read correctly and
setting it up on port 23456 like you specified.
We really should move the endpoint information to be sent out by the gr-log
system so you can redirect the info to a file and see the info without
requiring you to have access to stdout.

[Discuss-gnuradio] gr-specest dependencies
There are several dependencies for gr-specest not included in the recipe for pybombs and some not listed in the gr-specest list of dependencies but implied by the text. The recipe for gr-specest in pybombs doesn't include liblapack-dev, libblas-dev, and libarmadillo-dev. These include the list form the readme Howto build: In order to sucessfully build the gr-specest modules you will need: * cmake 2.8 * swig * libgnuradio-core * libuhd * gfortran (others might work as well, not tested) * liblapack-dev * libblas-dev but it will not compile, giving you an error about not finding BLAS and then you fix it by including armadillo which the readme wishes was deprecated, but most certainly is not. include: libarmadillo-dev on Ubuntu. Now, to construct some use cases that others can use like a guide post to what should be one of the most important gnuradio add-ons and wish I hope will help others use it. I will post stuff to my blog when it is ready.

I assume you meant 28e6, rather than 28.

Re: [Discuss-gnuradio] ColtrolPort IC Timeout
Hey Tom,
Yes, it was definitely pulling the correct endpoint. Even though it is
backgrounded, I have a log for everything that ran.

[Discuss-gnuradio] Window-close not killing everything
I have a user of simple_ra that has an issue with pieces of it still running after they use the window close button. In particular, there's an XMLRPC server thread that gets left behind. On my own, Fedora 14, system here, it's not a problem. Window close kills everything. On his Ubuntu 12.04 system, it seems to kill off most of it, but there's this dangler that is holding the XMLRPC socket. If I bind a close button to a function that issue a signal-to-self, what signal should that be?
